Why are Mn2+compounds more stable than Fe2+ towards oxidation to their +3 state?
Electronic configuration of Mn2+ is [Ar]18 3d5.
Electronic configuration of Fe2+ is [Ar]18 3d6.
It is known that half-filled and fully-filled orbitals are more stable. Therefore, Mn in (+2) state has a stable d5 configuration. This is the reason Mn2+shows resistance to oxidation to Mn3+. Also, Fe2+has 3d6 configuration and by losing one electron, its configuration changes to a more stable 3d5 configuration. Therefore, Fe2+ easily gets oxidized to Fe+3 oxidation state.

easy to understand
your answers are great but i would like to suggest that you should give the answer in such a manner that we can scroll down because here at each step we have to click which is time consuming
Question is different it is asking why mn+2 is more stable but your answer says that Fe is more stable
Best
grt
But in question fe+2 is more stable than MN+2,why,total chemistry is wrong.total exceptionð¿
Best explain
Very useful, thanks
Thanks
Good answer helpful
